Series 2a brakes. Or current lack of..

I fitted a new master cylinder a couple of months back, the bleeding of which proved nigh on impossible (lacking a forklift to stand the thing on it tail!) so i handed it over to a local landrover garage to sort out.

All credit to them they managed however it took a fair few hours of fiddling to get the pedal travel/freeplay balance so they didnt jam on or the pedal just hits the floor. Im sure i cant be the only person to use a red light to make a quick adjustment..

However now the brake lights pressure switch has failed, fitting a new one took 5 minutes - now on to bleeding the brakes.. 1st bleed nipple rounds instantly, 2nd sheared off (using a 4' long ring spanner). Problem.:doh:

Considering the brakes where bled this side of christmas and it has been mostly barnstored i wasn't expecting to shear anything!

Is is possible to remove the remains of the nipple? Any tips on how to remove a seized/rounded bleed nipple?!

Given i have had to resort to blowland/impact driver to even get at the 1st one im not relishing taking all 4 off!

Will post some pictures soon.

treat yourself to some new cylinders, complete with nipples and save yourself the hassle

Thats the current plan, and copper grease everything when i put it back together.

Hi,

In your situation, I would attempt to bleed from the middle of the system. Might work, might not.


Get mate to depress brake pedal and hold. Slacken brake light switch until fluid starts to dribble out. When it stops dribbling, tighten switch, pedal up, pedal down, slacken switch, ad infinitum...... Cease when no further traces of air. Wash brake fluid off bodywork.

Test. If it hasn't cured the problem .....identify easily accessible union down stream from switch, try again at that point. Problem is that you have a dual line system, which causes me problems with understanding the bleeding method. I understand the theory, it just that my arms are not long enough.

OK, even if this works, its only a temporary measure, as you still have two knackered wheel cylinders. But it might keep you mobile.

I usually manage to change stop lamp switches without bleeding. Fluid has to come out before air can get in, so you have to work fast.
